I am attempting to change the icon of the event clicked on, and restore the
previous events icon.
I am ok with the first part, but have been unable to access the icon of the
previous event to change it!
Sorry I have seen lots of examples (particularly from Mike Nosal) which
almost get me there, but not quite.
Code is as follows:
<script type = "text/javascript"> // script to override the default
bubble EventPainter script
Timeline.OriginalEventPainter.prototype._showBubble =
function (x, y, evt) {
document.getElementById('bob').innerHTML = "";
// Get previous Icon from storage
var objHiddenfield = document.getElementById("<%=
currIcon.ClientID%>");
var prevIcon = objHiddenfield.value // ok
// Get previous Id from storage
var objHiddenfield = document.getElementById("<%=
currId.ClientID%>");
prevId = objHiddenfield.value // ok
// Get current icon and ID
currentIcon = evt.getIcon(); // ok
currentId = evt.getID(); //ok
// Here with Current Icon and Id; and previous Icon
and Id
// Restore previous icon
// First get the EventSource object for previous event
var es = tl.getBand(0).getEventSource();
X = es.getEvent(prevId);
alert(X) // shows [object
Object]
//??? HOW DO GET/CHANGE icon of this event ?????
// Save current Icon and ID
document.getElementById('<%=
currIcon.ClientID%>').value = currentIcon document.getElementById('<%=
currId.ClientID%>').value = currentId
// Change icon of current event to rainbow
evt.setIcon("http://testtlc.timelinecontinuum.com/icons/rainbow.png";);
var themeBubble = this._params.theme.event.bubble;
// get the parameters for creating the bubble
evt.fillInfoBubble(bob, this._params.theme,
this._band.getLabeller()); // add content to the div. This will be the
content of the bubble.
tl.paint();
};
</script>
Spent a lot of time on this and I believe it shouldn't be as hard as I've
made it!!
TIA
